Abstract

The invention discloses a highly corrosive water-based aluminum-silver paste and a preparation method thereof, comprising the following steps: S1, taking an equal amount of solvent-based aluminum-silver paste and acetone, and mixing them according to a mass ratio of 1:1, and then mixing the mixed The solution is placed in an ultrasonic machine, and after ultrasonication for 15 minutes, the fatty acid on the surface of the solvent-based aluminum silver paste is removed by stirring and cleaning, and the solid aluminum silver paste is obtained after suction filtration and drying; S2, taking 13-18 parts by weight of tetraethyl orthosilicate, and then Add 26-36 parts by weight of absolute ethanol for dilution to obtain mixed solution A. By mixing the aluminum-silver paste solid and the aqueous solution of graphene oxide and putting them into the reaction kettle to react, and adding the mixed solution A and the mixed solution B dropwise during the reaction, the prepared water-based aluminum-silver paste is the surface of the aluminum-silver paste Coating SiO2 / GO composite film, through the shielding effect of SiO2 / GO composite film to achieve high corrosion resistance, so that the water-based aluminum-silver paste has high corrosion resistance.

Description

technical field [0001] The invention relates to the technical field related to coatings, in particular to a highly corrosive water-based aluminum-silver paste and a preparation method thereof. Background technique [0002] Aluminum silver paste is the most widely used metallic pigment with silver-gray metallic luster. As people pay more and more attention to environmental protection, aluminum powder that can be applied to water-based systems, that is, water-based aluminum-silver paste, has also received a lot of research. Aluminum-silver paste has a unique environment-friendly function, and can be widely used in water-based coatings and water-based inks. Water-based aluminum-silver paste can not only make the film-forming material have the advantages of acid resistance, alkali resistance, and high temperature resistance, but also has the advantages of metallic luster, hiding power, etc. Comparable to oily aluminum silver paste. [0003] However, because the existing water-b...
